Go to the frequently asked section on pump shoe installation/sealing, and intake grate alignment. Minor adjustments on your pump and hull components can make very positive changes on a GPR. Also take a look at stepped sponsons, transom plate alignment, and alignment of your exit nozzle (also know and described as "swing bucket").

These minor mods can help in hook up, stability, and to a minor degree, top speed.

Welcome to Green Hulk. What lake do you ride on? lake EL Guavio 6000 ft or Embalse De Tomine 8500 ft. El Guavio has some sweet fingers on it. Just looking at google earth. If you ride at 8500 ft there is allot of HP being lost. Water woody is the master of altitude if you mod the motor.

Hi, not riding at such high altitudes, but i've been there! The engine runs well but obviously not as it should, it lost a lot of power when I took it to the Embalse de Tominé. But i usually ride it in a little lake at 800 ft. The engine runs perfectly nice there...

I have road at a 6,000 ft lake up here in Oregon and the ski felt like it was running on one cylinder. So I could imagine at 8500 it would be a dog. Under 1000 ft my ski will run great too. Talk to you later.
